LP6216B6F

Preliminary Datasheet LP6216 High Efficiency 3A Boost DC/DC Convertor General Description Features The LP6216 is a current mode boost DC-DC converter.  Up to 94% efficiency Its PWM circuitry with built-in 3A current power  Shut-down current:1uA MOSFET makes this converter highly power efficiently.  Input and Output voltage Up to 24V  Internal Compensation, Soft-start  1MHz fixed frequency switching component sizes. The LP6216 features automatic  High switch on current:3A shifting to pulse frequency modulation mode at light  Available in SOT23-6 Package The LP6216 implements a constant frequency 1MHz PWM control scheme. The high frequency PWM operation also saves board space by reducing external loads.Highly integration and internal compensation network minimizes as 6 external component counts. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. The LP6216 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. VIN 4.7uH VOUT Diode C1 22uF C2 22uF SW The LP6216 is available in a small 6-pin SOT23-6 package.
